I have read some explanation on the internet regarding 3D to 2D coordinate transformations. However, as a newbie, after implementing some of the tutorials, I still don't quite get it.
Does anyone of you have an example of the application of coordinate transformations? Specifically, how does the depth changes as you rotate your views in gl_Control1?
FYI, I simply want to make a 3D canvas where the users can draw nodes by clicking on the canvas.
Thank you! Any kind of relevant comment is greatly appreciated!
